• If you are trying to use Boolean operators, they must be ALL CAPS: su sach y ((lang xa) OR (nang x)) hoi. hieu van cham xuc ((va hang) OR (van han)) tai va thiet.
• Adding a wildcard symbol may retrieve word variants: su sach y ((lang xa) or (nang x)) hoi. hieu van cham xuc ((va hang) or (van han)) tai va thiet*.
